Specification of Letters Patent.

Patented Aug. 19, 1919.

Application filed December 16, 1916. Serial No. 137.280.

To all whom it may concern:

Be it known that I, CHARLES B. KING, a citizen of the United States, residin at Detroit, county of Wayne, State of Michigan, have invented a. certain new and useful Improvement 'in Pumps, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanyin drawings, which form a p/frt of this speci cation.

y invention relates to air vacuum and gas pumps and an object of my improvements is to provide an improved form of positively operating rotary pump.

I secure this ob ect in the device illustrated in the accompanying drawings in which:

Figure 1 is a longitudinal section of an apparatus embodying my invention.

Fig. 2 is a section on the line B-B Fig. 1, looking from the right of said line.

Fig. 3 is a section on the line CC Fig. 1 with a partial section on the line C -C3 Fig. 1 superimposed.

Figs. 4 and 5 are views similar to Fig. 3'

showing the arts in different positions.

Figs. 6 and 7 are detail views showing alternative constructions.

a is an inclosed casing having laterally extending cylindrical parts a a, an eduction pipe a for gas and a drain pipe a for water. There is a chamber a in the cylindrical pr0 jection a with which communicates an induction pipe a for gas.

6 is a cylindrical casing having a shaft or arbor resting in bearings b and b in the cylindrical projection a from the casing 11. b b are apertures through a side wall of the cylinder 6 located radially at some distance from the periphery of said wall. The opposite side Wall of the cylinder b is cut away at its center as indicated at b b so as to surroundthe inner bearing for the shaft (l hereinafter described (l is a shaft resting in aball-bearing d at its inner end, extending laterally from the casing a and adapted to turn in a hearing at its outer end Whereit is provided with a stuffing box as shown. d is an opening extending into'the shaft d from its inner end, its Walls being coaxial with said shaft. (l 1s an opening forming a communication be tween the chamber a and the opening at at the inner end of the same.

a is a disk secured upon the inner end of the shaft (Z within the cylindrical casing b. This disk is provided with two peripheral grooves e and e and with a central chamber et Each of the grooves e and e is rovided direction of the hands of a watch as seen in Figs. 3, 4 and 5.

k 7.1 are apertures formed through the bottom of the groove (2 and forming a communication with the chamber 0 directly adjacent to each of the partitions y' j j upon the following side of said partitions.

f f f are lugs extending laterally from the outer wall of the disk 0 and so located that a straight tube 9 g or g may open at the outer end of each of said lugs. Each of said tubes extends forward and opens into the groove 0 through the bottom of said groove directly adjacent to the leading face of an adjacent partition j or 1' at approximately 120 degrees from the point at which it opens through the face of said lug.

I do not limit myself to the 120 degrees spacing but under certain changes in proportions I am able to vary this to increase and decrease the number of impulses per revolution by having a greater or less number of partitions and lugs.

Thus in this case each of the compartments into which the partitions y' j divide the groove 6 extends for approximately 120 degrees along the periphery of the disk 6 and the leading end of each of said compartments opens through apassage or aperture is 70 70 into the chamber e and the following end opens to a tube 9 g g which opens at its other end at a point approximately 120 degrees from said chamber to the outside of the disk e and the interior of t e casing b.

it indicates aliquid which may be water, mercury or other suitable liquid which is placed in the cylindrical casing b and may overflow into the casing a and be withdrawn through the drain pipe a For convenience I have indicated this liquid as water.

The shaft 03 is rapidly rotated as by an electric motor or other convenient power.

The action of the disk e upon the water throws the latter to the periphery of the cyl- The' inder I) as indicated in the drawings. casing I) also rotates thus obviating the fricr" 'tion and loss of power due to the relative It. a is a lug adapted to strike against av stationary part to limit the outward movement of the scoop 0 c is a nut by which the conduit 0 can be fixed in any desired angular position. When the inner surface of .the water reaches the'scoop c the water flows through the conduit 0 into the casing a and is withdrawn through the drain a.

The operation of the above described device is as follows:

The spindle d is rapidly rotated carryingthe disk 6 with it and causing the water it to-be rotated and forced to the periphery of the cylindrical casing b. Said casing is also rotated which maybe done automatically by the action of the water thereon until the angular velocity of the casing b, the disk 6 and the water his approximately the same. The disk 6 may be mechanically connected to the casing b in any well known way as by gearing as, shown in Figs. 6 and 7.

The disk 6 it will be noticed is eccentric to the casing b and therefore said disk a preaches the inner peripheral wall of said casing upon one side as for instance the top, as shown in Fig. 1 and recedes from the same toward the other side as indicated in said figure. i

As the disk e rotates the water enters and fills the compartments in the groove e at the top of said disk and is withdrawn from the same at. the bottom of the disk, as shown for instance in Figs. 3, 4 and 5.

Turning to Figs..3, 4 and 5 and observing the successive positions shown in said figures of the compartment of the groove 6 between the partitions j and j In the position shown in Fig. 3 the passage or aperture 7c is ust coming into position to be sealed by the water and compression will commence 1n said chamber upon the sealing of said pasthe induction pipe a the casing b and thence escapes through the aperture 12 into the casmg a and 1s dlS- charged through the pipe a I v The air discharged from the groove e passes through the apertures 6 into the eas- Tn the position shown in Fig.- 5'the passage 7c is just emerging from the sealing liquid and the air cavity is being enlarged in the compartment so that air is sucked in from the chamber. 6. which is supplied through the induction pipe (1 and passages d and d (Fig. 2).

Each of the compartments of the groove e and also each of the compartments of groove 6 passes continuously through the above described phases, and thus the apparatus is continually sucking the air fro-m the chamber. 6 and discharging it into the air space of the rotating cylinder 6 and thence into the casing a and thence out from The sealing points are marked a? and 3 on the dotted circle indicating the path of the outersurfaces of the lugs f f F.

Inasmuch as compression is continually taking place at the upper part of the-casing b the water level here will be forced inward making a more of the liquid.

To withdraw the heat from the air water may be sprayed into the incoming air and will be separated from it by centrlfugal force and discharged through the drain a.

' lit will be noted that the induction ports I: is? k are located nearer .the center than the discharge ends of the tubes 9 9 and 9 The relative location of these orifices both angularly-and radially is such that when the induction port commences to be sealed by the waiter annulus at the top, the corresponding discharge tube at its delivery end is just emerging from the water at the bottom of the casing b and when an intake port is just emerging from the water at the top the delivery end of the corresponding discharge tube is just entering the water.

positive seal at the surface The disk e extends below the surface of the annular body of water throughout its circumference and thus the outer opening from the grooves in said disk is continuously sealed.

What I claim is:

1. In an apparatus of the kind described,

the combination of a revoluble part having a cavity therein opening at the periphery of said part, a revoluble casing inclosing said revoluble part and having its axis eccentric thereto, and adapted to hold an annular body of water at its outer wall, a body of water in said casing, said cavity being provided with an intake passage and a discharge passage, said passages being so arran ed that the one passage shall be sealed by t e water when the other passage is within the surface of'the water.
